3mm Special-Shaped Bi-Color Through-Hole LED
3mm Specialty-Shaped Dual-Color LEDs - Hongcheng Optoelectronics LED Manufacturer
Product Overview:
The 3mm special-shaped dual-color through-hole LED uses a special-shaped encapsulant package containing red and emerald-green LED chips. Its 3-pin common-cathode structure allows each color to be switched and controlled independently, indicating different operating states at a single location. The through-hole lead design supports PCB and equipment-panel mounting, for dual-color status indication in instruments, meters, industrial controls, household appliances and communications equipment.
Key Advantages:
- 3mm special-shaped package for specific panel and assembly requirements
- Integrated red and pure green chips provide bi-color indication in a single LED
- Three-lead common-cathode structure with independently controllable colors
- Supports single-color illumination and color switching for easy differentiation of equipment status
- Displays two colors at one indicator position, simplifying panel indicator layout
- Through-hole leads simplify PCB mounting and soldering
- Lead length, bending and package configuration can be evaluated to suit project requirements
Applications:
- Instruments, meters and industrial control panels
- Equipment running, standby and fault status indication
- Household appliances and audio equipment
- Communications equipment and power supply status displays
- Bi-color indication for buttons, switches and controllers
- Panel indicator structures requiring a special outline
Product Features:
Chips: integrated red and emerald-green chips can be controlled independently by an external driver circuit for dual-color status display.
Package: 3mm specialty-shaped through-hole package. Check outline dimensions and installation clearance against the corresponding dimensional drawing.
Encapsulant: This version uses a diffused encapsulant. Other versions, including clear encapsulants, require confirmation against the corresponding part number's datasheet and samples.
Leads: Three-lead common-cathode structure with a shared cathode and separate red and green anodes. Confirm lead order and orientation against the datasheet during installation.
Customization: Color combinations, lens types, lead lengths and bending configurations can be evaluated for project requirements, with the specific solution confirmed through drawings and samples.
Packaging: packaging format, quantity and protection requirements are confirmed with the order. Supply arrangements are determined according to transport, storage and assembly needs.
